Abstract
The present invention relates to dental, light-curable, one-component composite compositions comprising (A) monomers, (B) fillers, and (C) initiators, the viscosity ηof which at 20° C. is greater than 400 Pa*s, preferably greater than 800 Pa*s and more preferably greater than 1200 Pa*s, and the viscosity ηof which at 50° C. is less than 150 Pa*s, preferably less than 120 Pa*s and more preferably less than 90 Pa*s, and wherein the quotient η/ηof the viscosity of the composite composition at 50° C. and the viscosity of the composite composition at 20° C. is less than 0.125, preferably less than 0.1. The invention is preferably directed to dental composite compositions selected from the group consisting of dental filling materials, lining materials, luting materials and fissure sealants.
